Abstract

Objectives: To evaluate and compare the remineralizing effect of biphasic calcium phosphate (BCP) powder compared to nanohydroxyapatite (nano-HA) and beta-tricalcium phosphate (β-TCP) powders using laser fluorescence.

Materials and methods: Fifteen sound human premolars and molars were subjected to infection control measures. Then, the roots were removed and crowns were sectioned to provide blocks from the buccal and lingual surfaces. Each specimen underwent pH cycling to produce white spot lesions. The specimens were divided into three groups according to the treatment used. The total sample size for all groups was thirty specimens (10 specimens for each group). The change in mineral content was evaluated by laser fluorescence using a DIAGNOdent pen at baseline, after demineralization, and after remineralization for 14 days and 30 days. The mean value of each specimen reading was calculated.

Results: Biphasic calcium phosphate showed lower laser fluorescence results compared to hydroxyapatite and beta-tricalcium phosphate (recorded by DIAGNOdent pen) after application for 14 days (8.04±0.55) and 30 days (6.08±0.65). However, the results were not statistically different from the results of other groups (HA group 8.18±0.87 and 6.36±0.922 and β-TCP group 8.36±1.17 and 6.93±0.81). The remineralizing potential of the three materials increased with increasing the time of application.

Conclusions: Biphasic calcium phosphate powder could be used for enamel remineralization. Its potential for the remineralization of incipient enamel caries is similar to hydroxyapatite and beta-tricalcium phosphate.
